GLAZING SPRIG.

Application filed March 15, 1926. Serial No. 94,699.

My invention relates to new and useful improvements in glazing sprigs, and has for its primary object to provide an exceedingly simple and effective device of this character which, when mounted in place will coact with panes of glass in such a way as to prevent endwise movement thereof.

Another ob ect of the lnvention is to form a sprig from a single piece of metal fashioned to provide flange, said body a glass to hold it a body with coacting with the face of in a glazing groove, while the depending flange coacts with the edge of the glass to prevent movement thereof.

1th these ends in view, this 1nvent1on consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains, may understand how to make and use the same,

will describe its construction in detail, re-

ferring by numerals to drawings forming in which:

Fig. 1, is a perspective the accompanying a part of this application,

view of portions of a'number of co-related glazing bars such as are used in green-houses,

panes of glass sh improved glazing with a number of own held in place by my sprigs.

Fig. 2, is an enlarged face view of a blank for forming one of the sprigs;

and

Fig. 3, is a perspective view of one of the finished sprigs for use on side of a pane of the left hand glass.

Fig. 4, is a similar view of another of the sprigs for use on the right hand side of the pane of glass.

In carrying ou embodied, 5 repre bars of a green-house,

ing one or more for the reception which are mounted shingles so that the lower end ing glass overlaps ceding one.

It is necessary to hold the glasses firmly a depending downward endwise in the frames or bars, and this is usually done with nail-like or flat sprigs, and ofttimes dependence is placed upon the pressure of the sprigs upon the glass to hold them in position, but for additional security, others of these ordinary sprigs are sometimes placed at the ends of the glasses, but this requires considerable additional work and is more often dispensed with.

In my invent1on it is desired to provide a sprig that will coact with the outer face of a glass in order to hold it in place under pressure, and also means that they will coact with the lower edge of the glass to prevent downward endwise movement thereof. To this end, I form a blank 8 from suitable fiat metal and fashion it so that the side edges 9 converge slightly outwardly away from the base 10 to a point intermediate the ends where they then abruptly converge to form a point 11. Next, one side of the blank is then bent atright angles upon the line 12 so as to form a body 13 and a depending flange 14;, the forward edge .of which is beveled as at 15, due to the angle of the edge of the point. These several angles make it easy for the sprig to be driven into or glazing bars.

In practice the sprigs are made in right and left handed ways as shown in Figs. 3 and 4c, and are placed upon a pane of glass at the bottom exposed edge so that the body lies flat on the outer face of the glass and theflange overlies the edge thereof, and when the sprig is driven into the woodwork the glass will be held in its groove by the body, and will be retained against downward endwise movement by the flange. This flange will also coact with the underneath the exact details of construction as herein thewoodwork of the sash, frame Eli) shown as these may be varied within the limits of the appended claim without departing from the spirit 0]": my invention.

Having thus fully described my invention, What I claim as new and useful is:

A glazing sprig formed from a fiat piece of metal so fashioned as to have a base edge, two side edges slightly converging toward the ends furthermost from the base affixed my signature.
